expand (7x(4x+7))/((7x-4)^2)

expand

\frac{7 x ( 4 x + 7 )}{( 7 x - 4 ) ^{2}}

\frac{28 x ^{2} + 49 x}{49 x ^{2} - 56 x + 16}

Solution steps

\frac{7 x ( 4 x + 7 )}{( 7 x - 4 ) ^{2}}

(7 x - 4)^{2} = 49 x^{2} - 56 x + 16

= \frac{7 x ( 4 x + 7 )}{49 x ^{2} - 56 x + 16}

Expand

7 x (4 x + 7) : 28 x^{2} + 49 x

= \frac{28 x ^{2} + 49 x}{49 x ^{2} - 56 x + 16}

\frac{( x ^{2} - 1 ) e ^{x^{2}}}{2}

12 \cdot 4 \frac{1}{2}

- 4 sin (2) (x + \frac{π}{2})

(l^{2} - 1 + e)^{2}

\frac{( 3 x + 2 ) ( x + 3 )}{2 x + 1}
